Evolutionary, Comparative and Functional Analyses of the Brassinosteroid Receptor Gene, BRI1, in Wheat and Its Relation to Other Plant Genomes.

ABSTRACT: Brassinosteroids (BRs) are plant hormones, fundamental for the growth and development of plants. A trans-membrane protein receptor kinase, Brassinosteroid-Insensitive 1 (BRI1), is known to interact with BRs and be directly involved in plant development. This study investigates the structural organization of BRI1 orthologs in several taxa, with a specific interest in Triticum aestivum. True orthologs of Arabidopsis thaliana BRI1 (AtBRI1) from seven-plant species showed sequence identity ranging from 54% to 95% at the protein level. All gene sequences lacked introns, leading to speculation that post-transcriptional processing in TaBRI1 is similar to AtBRI1. Based on in silico analysis, a single copy of BRI1 was present in each of the three wheat genomes on the long arm of chromosome 3. Domai
